WordPress Video Plugin

I am using a Theme called ‘Max’ (http://deluxethemes.com/2013/07/21/max-wordpress-theme-download/) Also I installed ‘WordPress Video Theme” (http://wordpress.org/plugins/wordpress-video-plugin/). When I activate the Plugin it shows an error.

‘Plugin could not be activated because it triggered a fatal error.

Fatal error: Cannot redeclare novamov_plugin_callback() (previously declared in /home/dawah2/public_html/wp-content/themes/max/lib/supported-video-sites.php:107) in /home/dawah2/public_html/wp-content/plugins/wordpress-video-plugin/videos.php on line 300′
